IMPROVEMENT `IIIN' ROTATING OSCILLATING BTEAMVALITS- I AToftll whom it may concern:

Be it known that I, CHARLES F. HADLEY, of Chiecpee, in the county of Hampden, and State of Massachusetts, have invented a new and improved Valve;

- and I do herebydeclare that the following is a full,

clear, and exact .description of the constructionand operation of-tbe same, reference being had to the ac companying drawings, making a part of this speciica Y tion.

- This valve is designed for steam-pumping and other engines, where .no rotary motion is required. Also for water-meters.

The object of this invention is to produce a continual reciprocating motion, by overcoming dead-points, or centres, in pumping and other engines.

Figure 1 is a longitudinal section, taken through the line a, b on iig. 2.

Figure 2 is a transverse section, taken through the line c fl 0n iig. 1.

Figures Sand 4 are-details of the valvepindle O, with arms D D, tapering toward the top.

' Figure 5 is a detail of the cam E and lugs F F, with the tappet G, spiral spring H, and lever I'.

The valve-chest A is cast with induction-ports L L, and exhaust-port M, and bored to receive the valve B, through which is cut a groove for the valve-spindle O,

which is fitted to revolve freely until the arms D D come in contact with and operate the valve B, giving a'slight motion to the valve-spindle before operating the valve, the valve-spindle passing o'ut through a stuifing-box in the usual Way.

Upon the end of the valve-spindle C, is fitted rmly the lcam E, under which is cast on the cylinder a projection to receive the tappet G andv spiral spring H, for throwing the cam E over the centre.

The tappet is bevelled from the centre each Way.,`at

the top, andadjusted by check-nuts below.

The caurE is operated by lever I, secured to the' cylinder by the stand J, and connected to the pistonrod by a connecting-rod and arm, in'the usual way.

Introduce steam to the valve-chest A, through the pipe N, when it enters the cylinder, moving the piston until the lever I strikes one of the lugs onv the cam, moving it a short distance before operating the valve, and as the piston nears the end of the stroke, the ports are closed by the time the cam has passed the centre, bringing the spring in operation, opening the opposite port, and reversing the engine.

By this device the valve-spindle has a greater .motion than the valve, and-whenthe valve is on the centre, the cam has always passed the centre, making it impossible to ever have the induction-ports both remain closed while the power is attached.

vHaving thus described my invention,

What I claim as new, and desire to secure by Let- 1 ters Patent, is-" 1. The valve-spindle O, constructed with tapering
